Functions
template<typename A> requires (is_regular_or_view_v<A>)
auto	nda::mpi_reduce (A const &a, mpi::communicator comm={}, int root=0, bool all=false, MPI_Op op=MPI_SUM)
	Implementation of an MPI reduce for nda::basic_array or nda::basic_array_view types.
template<typename A1, typename A2> requires (is_regular_or_view_v<A1> && is_regular_or_view_v<A2>)
void	nda::mpi_reduce_into (A1 const &a_in, A2 &&a_out, mpi::communicator comm={}, int root=0, bool all=false, MPI_Op op=MPI_SUM)
	Implementation of an MPI reduce for nda::basic_array or nda::basic_array_view types that reduces directly into an existing array/view.
